Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a wheelchair for going up and down a side road with a novel configuration.

Conventional wheel-only wheelchair t has a pitching capacity of 8 even with an electric wheelchair.
M is the limit, and as a result, the occupied area and construction costs of side passageways attached to buildings become large, which undeniably becomes a bottleneck in considering architectural plans for buildings used by wheelchair users. It cannot be overlooked that wheelchair users who live in urban areas with many slopes are required to have a helper when they go out, and that there are many restrictions and influences on their behavior.

The present invention is intended to fully solve such problems, and the details of one embodiment of the present invention will be described below with reference to the drawings.
I will clarify.

car 1 is one sideway lift door of the present invention. and.

The structure is as follows: *In a wheelchair body 2 in which a large traveling wheel 2C having a hand changer 2B is arranged on a chair frame 2, a hub 2 supporting the large wheel 20 is provided.
A C gear 3 and a lifting gear 4 that are linked to the rotation of the large wheel shaft 2C are fixed to D, and a shaft 5BK is a caterpillar drive wheel for driving a caterpillar that is linked to the gear 5 at the rear and lower part of the frame 2A. When 5C is installed, the shaft 5B has a rib 6t extending in the front direction of the frame 2A. Rotatably connected and supported,
The lip is equipped with a suitable number of caterpillar gears 6M and a caterpillar driving wheel 6Bk' rotatable tllij, the gear 6A is connected to the drive gear 5 by a chain 60, and the drive wheel 50 and the drive wheel 6B are connected to the drive gear 5 and the drive wheel 6B. A caterpillar belt 6D is hung on the frame 2, and a lifting frame 7 having a substantially H-shaped side surface is attached to the front part 5+ of the frame 2 so as to face the lifting gear 4. On the circumferential surface, a rising/falling shaft gear 7A is attached to the side so that it can be raised and lowered freely.

The relationship between the lifting gear 4 and the lifting shaft gear 7 is related to I.
8i! Connecting gear B IN freely arranged
The gear operating lever 8m is rotatably connected to the lower frame 2A of the frame 2m in a direction orthogonal to the front and rear directions of the frame 2m, and 10,000 of the levers 8 are configured to swing by grooves 9A of a gear operating lever plate 9 provided in the upper frame 2A'' of the frame 2.

7B is a stopper for fixing the lifting shaft gear 7AV to the frame 7 at a predetermined height; The screw s7B screwed into the above lift shaft gear 7 moves forward and backward.
It is designed to tighten the system. 10 is a brake.

In addition, the side road (slope) elevation setting angle fV is 20 degrees, and this is Kl! The mileage is approximately 90, which is half the circumference of the large wheel.
It is a preparation.

Next, the method of using the present invention will be explained together with its effects.

Muro Flat floor running leg (with caterpillar storage) A, turn the lifting shaft gear lever '@ON, loosen stopper 7B, turn the hand rim in the forward direction, and raise the lifting shaft gear.

B, Stop line of the caterpillar shaft (1 between the bald part and the caster)
IA), turn off the lift shaft gear lever, set the stop bar to -1 gear, and tighten the stopper 7Bt''.

The operation buttons of 6 and above have little influence on the casters, and the large wheels and casters allow the wheelchair to move forward and backward without any trouble as the hand rim rotates.

B. Traveling on a new road @ (for caterpillar delivery) A. Set the elevator shaft gear lever YON, loosen stopper 7B, turn the nohen rim in the reverse direction, and lower the elevator shaft gear.

B. Adjust the caterpillar axis to the side road angle, and the horizontal angle t of the wheelchair.
tat, turn the lift shaft gear lever vOFF, engage the stop bar gear, and tighten stopper 7B.

The caterpillar adapts to the side road by the above operation, and the wheelchair can be freely moved up and down the side road by the caterpillar according to the rotation of the hand rim without the vehicle body moving up or down. Forward and backward movement using the hand rim is the same as in the case of the above-mentioned arm.

C1 reclining (using caterpillar) A, lift shaft gear lever 4ON, stopper 7Bt? Loosen it, move the hand rim back 1 mL, and lower the elevator shaft gear.

Arbitrarily determine the vehicle body angle g according to the ground contact of the mouth and caterpillar,
Elevating axis gear lever at the time of angle determination? ! -0FF, engage the stopper 2 gear, and tighten the stopper 7B.C By the above operation, the vehicle body can be reclined at any angle.

D. On a flat floor, it can be reclined by operating the caterpillars, and by attaching ski directional snakes to the casters, the caterpillars can be used as ski slope skis instead of skis.
